yes, we can design such two dices.  the first one is a normal die  with six faces which have digit   1,2,3,4,5,6 respectively.  the second die is a special die.  three faces from it have digit 0  and the other three faces have   digit 6.  when you roll these two dices, the  probability that the sum of the  numbers appearing on their faces   is equallly likely to be any number  from 1 to 12, namely  p_(sum=1) =p_(sum=2) =...=p_(sum=12) =(3/(36))=(1/(12))
